TO ALL TO WHOM THESE PRESENTS SHALL COME: y

Be it known that I, JAMES D. SUMNER, of Lexington, in the county of llIiddlesex-,vand'Stateoi` Massuehm` setts,.have invented an improved Water-Meter; and do hereby declare theriollowingto be zafull, clear, und exact description thereof, reference being had to the accompanying drawings, making part of thisspeeiiication, )and in n'liicbi Y d Figure 1 is a vertical and longitudinal, and` ,Fig'nre 2 is a vertical and transverse section of a water-meter constructed in 'accordance with my invention. Figure 3 is a side elevation of its interior or liquid-measuringchamber. i i v l "lheobject of this invention isl to prbduceadurable and reliable apparatus for measuring the volume of liquidpzassing through aipipe, one great object next to its accuracy und durability beingits simplicityand consequenitl'chenpnessof`construction, this being a great desideratum, whether used in great numbers by companies, er hy'individuals and .for family use.- l

Theinvention consists in a circular box or. case,` having a 'rotatingV disk or drum disposed within it eccentrica'lly, supplied'iyith a number of vanos applied to it, the wholebeng as hereinafter described and referred to. In-.th drawings above referred toArdenotes a circular box or case, having an inner cap-plate, a, and an outcrcover, bl, applied't'o it, as shown in g. 2, and provided with inlet and outlet pipes or ports, a3, b3. Within the case A, a. disk'or drum, B, is situated, and so as to rotate freely uponV a stationary stud or standard, c, extending from Ytheinner-face of the case A, this pin c being situated eccentrically with respect to thecnse A, assit-own in gs.- land 2 of the drairings," or so as to leave considerable space between the lower edge of the disk B and the bottom ofv the ,ch'amber'a1 of the case series of pendulous floats or vnn'cs, e e e, 85e., is hinged to'the periphery of the-diskB in 'such manner that their free extremities shall 'drop by their own gravity 4(or be thrown by centrifugal force generated by the revolutions of the disk) against the interior surface of the chamber ai of the case A, this'chambei having at its `upper part a recess or extension, a2, leading out of it and `'ma-kingpart of it, this recess a2 forming an arc of' a circle whosev radius is less than that of the chamber al, but i equal-'tb that of thedisk'B and its vannes, `the same being in order that the outer surface of -two or thereabouts -oi'y thevanes shall rotate in close proximity to or against the boundary of the said recess, and prevent the passage of 'any great amount ofliquid between Vthem,'whichiwould not ue the ease were the recess a2 of thesnmo radius as thht of `the chamber The inner wall ot' the case-chamber a, as well as the inner fece of the capplatea, has a circular groove, "g, cu-t in it concentric with the stud c, this groove being for the reception. of a fin or. lip, r, formed upon each side ofthe disk B, as shown in iig. 2 of the accompanying drawings, the object of the groove and lip being to prevent the passage ofvwater or other matter around the axis ot' the disk. A suitable indicatingmechanism to indicate the number of' revolutions of the disk B is to be suitably attached to the apparatus. The 4current ol' waterf or other liquid-rushing into and through the case A by the inlet a3 and outlet b3, will impinge against the upper surface ot' 'the vane `next adjacent to and below the inlet opening a3, and put the disk B in revolution, each successive vane, as it passegbeyond the inlet, being subjected to -the action of the owing liquid,'and receiving an impetus therefrom", thus -keeping up a continued revolution of the disk. The amount of liquid passing through Vthe case A at each revolution of the disk being determined, and the indicator giving the number ofits revolutions, the flow of liquid is determined with great accuracy. As this indicating mechanism above referred to is similar topthers non' in use, and forms no part of my invention, Ihave not deemed it necessary to exhibit it in the drawings. It may be found in practice that the vanes will adhere by capillary attraction tothe periphery of the disk B, and allow the liquid to pass through the case A Without rotating it. To remedy this djicultyithe periphery of the said disk may bescoredfor recessed beneath the vanos, as shonjn in iig, 4 ofthe drawings, which is a 'section of a portion of the disk and its Yanes.

The above-described meter may be applied to advantage to liquor-estaban as well as te vessels of various descriptions for holding liquids. l i

i j I claim the combination of the disk B, flanged or tongued at or near its periphery, and carrying the vanos, or ilouts e, with the case A recessed and grooved in its interior, substantially in the manner and'for the purposes herein set forth.
